Antinuclear

The largest solar farm in the southern hemisphere lies on arid land at the foot of the Flinders Ranges, more than 300km north of Adelaide. If that sounds remote, it doesn’t do justice to how removed local residents feel from what currently qualifies as debate in Canberra.

As government MPs and national newspapers thundered over whether taxpayers should underwrite new coal-fired power, mauling advice from government agencies as they went, residents of South Australia’s Upper Spencer Gulf region have been left to ponder why decision-makers weren’t paying attention to what is happening in their backyard.

In mid 2016, this region was on the brink, hit by the closure and near collapse of coal and steel plants. Now it’s on the cusp of a wave of construction that investors and community leaders say should place the region at the vanguard of green innovation – not just in Australia but globally. There has been an explosion in investment, with $5bn spread over the next five years. There are 13 projects in various stages of development, with more than 3,000 construction and 200 ongoing jobs. The economy of this once-deflated region has been transformed and those who live here are starting to feel hopeful again….

In simple terms, the Upper Spencer Gulf transition story goes like this.  ……

At the same time, further around the gulf, the steel town of Whyalla was teetering precipitously after the owner, Arrium, put the mill in voluntary administration facing debts of more than $4bn.

Yet as the doom hit, there were also rays of hope as several clean power projects were mooted for the surrounding area.

Two years on, the Port Augusta city council lists 13 projects at varying stages of development. And Whyalla has unearthed a potential saviour in British billionaire industrialist Sanjeev Gupta, who not only bought the steelworks but promised to expand it while also spending what will likely end up being $1.5bn in solar, hydro and batteries to make it viable.

Gupta says the logic behind his investment in solar and storage is simple: it’s now cheaper than coal.

Johnson says he expects the Upper Gulf region to receive $5bn in clean energy investment over the next five years. “My gut feel – and I’m an optimist – is that they will all go ahead,” he says. “They are different technologies and they are playing in different markets, so they are not competing for power purchase agreements.”By any measure, the Bungala solar power plant is vast. Once its second stage is complete, 800,000 photovoltaic modules will cover an area the size of the Melbourne central business district……

Bungala is nearing completion, with work on the $425m plant expected to be finished by January. Its first section started feeding into the national electricity grid in May. Further west, ground has been broken on the 59-turbine, 212MW Lincoln Gap wind farm, though progress has temporarily stalled after developer Nexif Energy discovered unexploded ordnance from historic military testing on site.

As Guardian Australia visited the region, the South Australian Liberal government gave final approval for a $600m hybrid wind-and-solar energy park on the south-eastern edge of Port Augusta that proponent DP Energy says will be the largest development of its kind in the country. A second stage with more solar and a 400MW battery is slated to follow.

The world is going slow on coal, but misinformation is distorting the facts

At Cultana, just north of Whyalla, Energy Australia is investigating building the country’s first saltwater pumped hydro energy storage plant. It would draw water from the Spencer Gulf, pump it uphill when energy is plentiful and cheap, and convert it to hydro electricity at times of high demand. A decision on the project is expected in 2019.

All are potentially agenda setting, but none are as anticipated as the Aurora solar thermal power station. It is the culmination of a push that began in 2010. A research paper by advocacy group Beyond Zero Emissions formed the basis for the creation of Repower Port Augusta, a community group that built widespread support for bringing the developing technology to the region among councils, business and unions.

US developer SolarReserve took notice. It plans to use a field of mirrors to heat a molten salt system inside a 234-metre tower. It will both generate electricity and store eight hours of energy that can be sent out when the sun isn’t shining. The company says the $650m plant, to be built at the Carriewerloo sheep station about 30km north of Port Augusta, will be the world’s largest solar tower with storage and provide 5% of the state’s energy needs.

Aurora is not the only solar-thermal project linked to the region. Port Augusta is already home to a small concentrated solar-thermal plant owned by Sundrop Farms that it uses to run a hydroponic greenhouse that provides Coles with tomatoes.

Also on the horizon, and just as unique design-wise, is a proposal by Solastor, chaired by former Liberal party leader John Hewson. It promises new graphite-based technology to capture solar energy and store it in a load-shifting battery. Hewson says it will be a world-class project. “Solar thermal will take the market, there’s no doubt about that,” he says.

Why are developers choosing the Upper Spencer Gulf? Investors say it has several things going for it: great sunshine; a history of electricity generation that left strong connections into the national grid; nearby industry – particularly mine developments – demanding reliable energy; strong facilitating support from the Weatherill Labor government that has continued under the new Liberal premier, Steven Marshall.

…………“The Upper Spencer Gulf happens to be a very good place to start,” Garnaut says. “Some coal generation regions have good renewables and others don’t, and no others have them as good as Port Augusta. [But] the Port Augusta developments could be replicated in any region that has good solar and wind resources.”

The inclusion of solar thermal is crucial as it means jobs on a semi-industrial scale. Wind and solar photovoltaic plants bring plenty of jobs in construction, but few in operation. Solar thermal has more in common in operation with coal, using steam to spin a turbine. SolarReserve expects to have a 50-strong permanent workforce at the Aurora plant. …….https://www.theguardian.com/environment/2018/jul/20/life-after-coal-the-south-australian-city-leading-the-way
